But although a few candidates drew strong opposition, many supporters of the top-tier candidates were comfortable with the possibility of other top-tier candidates getting the nomination. About one-fifth of people who were at least considering Booker, for example, would have a problem with Warren or Sen. Amy Klobuchar as the nominee. Sanders, however, is deeply unpopular among supporters of just about all the other top-tier candidates -- about half to three-quarters of activists who supported one of the eight candidates who were ranked the highest in the first table would not want to see Sanders win the nomination. Biden, too, is unpopular among supporters of Booker, Warren and Sanders, again garnering around 50 percent opposition. Most Sanders supporters, meanwhile, were opposed to Klobuchar, Biden and Sen. Kirsten Gillibrand.
